The flat sided bushing serves as a means for connecting the bracket and panel, as a meansv for -securing f the parts against angular displacement under load of the instrument andwiringattached thereto, and as a means throughwhich'the reciprocable actuating rod 44 may operate.

I claim: .e

1.The combination with a bracket having first and second angularlyv -related apertured arms, of mounting means for the first arm comprising a tubular bearing, a rod movable through said bearing and provided with a handle, said rod being approximately parallel to the second -arm of the bracket, van instrument mounted on said second bracket arm on the face thereof opposite to the first bracketarm and including a rock shaft projecting through the aperture of said second arm toward said rod, a crank on said rock shaft at the. side'of said .second arm opposite to said instrument and between said second arm and` said rodyand means connecting said rod with said crank for the operation of said instrument rockshaft. Y

2. The combination with an apertured panel, of a bracket secured to the panel and provided with an aperture registering with that of the panel, means in said apertures mounting said bracket to said panel, said bracket having an arm extending rearwardly from the panel at one side of the `aperture therein, an encased instru- Amentmounted wholly onsaid arm and provided With'an operating shaft projecting across the plane of the armltoward a position of alignment with said apertures, crank means on said shaft, and a rod reciprocable through the apertures and operatively7 connected with said crank means for the manipulation of said shaft.

3.r The combination with an apertured panel, of a bracket secured to the panel and having an arm projecting rearwardly in Aa plane substantially normal to the panel and at one side of the aperture, ank encased instrument unit supported by the bracket armwholly at the side opposite said panel aperture, a rockshaft operatively connected for the actuation of said unit and projecting therefrom toward the plane of the panel aperture, and an actuating rod reciprocable in the panelaperture substantially in said yplane and operativelyfconnected with said rock shaft for the operation thereof, the'disposition of said instrument and rod at oppositesides of said bracket arm being adapted to reduce bending strains to which said arms would otherwise be subject in reciprocation of said rod.

4. The combination with a panel and an L- shaped bracket having registering apertures, of a bushing extending through saidvv apertures and splined to said panel and bracket, means on said bushing for maintaining said panel and the apertured arm of said bracket in predetermined relation, a rock shaft approximately parallel to said panel at a point on the other arm of said bracket remote from said panel, an encased instrument "panel engaging arm and an instrument supporting arm, of a bushing for mounting said panel engaging arm, said bushing having a central opening restricted as to diameter near its outer end, an instrument operating shaft carried by said instrument mounting arm and provided with a crank in substantial alignment With said panel, and an actuating'shaft extending through said bushing and bearing in the restricted internal diameter thereof, said rod being connected with said crank and Vaccommodatedras to non-rectilinear movement by the enlarged internal diame- 'bushing having a relatively large internal diameter except at its outer end where its diameter is constricted, and an operating rod having a bearingin the constricteddiameter of ,said bushingV and connected with said crank for the oscillation of said rock shaft.v

'7. In a device of the character described, the combination with a panel and bracket arms having registering openings, of a second bracket arm projecting rearwardly from the first and from the panel, a rockshaft carried by said second bracket arm andprovided with a crank, an instrument carried by said second bracket arm at the side thereof opposite said crank, a bushing connecting said paneland bracket arm and extending through their registering apertures, said bushing having -a relatively large internal diameter except at its outer end where its diameter is constricted, and an operating rod having a bearing in the constricted diameter of said bushing and connected with said crank for the oscillation of said rockshaft, together With means providing ank axially adjustable connection between said rod and crank whereby said rod may be adjusted as f to its initial position with respect to said bushing.

8. The combination with a panel mountingr bracket having first and second arms substantially at right angles to each other,'each of said arms being apertured, of a panel having an aperture registering with that of the bracket,'a tubular bolt extending through the apertures of panel and bracket, a nut threaded to said bolt anchoring one arm of said bracket to the panel, a rod reciprocable through said bolt and provided with an arm externally of the panel, an instrument casing mounted on the second arm of the bracket in spaced relation to the` panel on the side of said arm opposite to said rod,ran instrument wholly housed Within said case, an operating shaft for said instrument extending from Said case through the aperture of said second bracket arm toward said rod, a crank on said rock shaft, and means connecting said rod with said crank.

9. The combination with a panel and panel bracket having registering non-circular apertures, of a headed bushing corresponding in section to said apertures and engaged therein, said bushing having a threaded portion behind said bracket, a nut engaging said threaded portion and securing said bracket to said panel, a rod reciprocable through said bushing and having a handle externally of said panel, said bracket 'having an apertured arm projecting rearwardly of said panel and substantially parallel to said rod, an instrument casing riveted to the face of said bracket arm opposite said rod, an instrument housed Within said casing and provided With a rock shaft projecting through the aperture of said bracket arm and provided with a crank between said bracket arm and rod, and means connecting said bracket arm and rod for the oscillation of said rock shaft in the course of reciprocation of said rod, said bracket, bushing and nut providing a single hole mounting for the support and actuation from said panel of an otherwise conventional instrument requiring an oscillatory movement for its actuation.
